This challenge gives you the possibility to use Pokèmon that are underestimated, to say, Dunsparce, Shuckle, and similar. Obviously you can use your common sense to choose the ones to use, just avoid using things like Charizard, Mewtwo and others.
I won't follow the competitive tiers, like UU, NU, BL, and similars.
I'll make a list based on my own choices, then we can discuss if you want to add/remove something.
That said, here are the rules!

1. You can use only Pokèmon that are included in the list (if you didn't understand it :P)
2. Obviously, no Legendaries. You can still catch them, if you like.
3. Hacking is allowed before you get your second Gym Badge: you can either hack Pokèmon or Items, just do it before the limit, and obviously hack something unevolved and at the level of the Route/Cave where you do it.
4. Egg trading is allowed.
5. HM Slaves are also allowed.
6. You defeat the game according the following conditions:
- G/R/B/Y/R/S/E/D/P/B/W: Defeat the Pokèmon League champion.
- FR/LG/Pt: Defeat the Pokèmon League champion twice.
- G/S/C/HG/SS: Defeat the Pokèmon League champion and Red. (For HG/SS users, defeat the League also when they're stronger).
- Colosseum/XD: Defeat Evice/Greevil.

Actually, I've hacked all of my team members in Route 1.
So I've got a Lv. 4 Exeggcute, a Lv. 3 Shuckle, a Lv. 4 Torkoal, a Lv. 4 Finneon, a Lv. 4 Vullaby, and a Lv. 5 Mew. Now I'm at the entrance of Chargestone Cave.
Oh yeah, before I forget, I traded my guys over to my White version, where they got some nice items and TMs/HMs.
